Abstract: An integrated device in an HVAC system is configured to modify an environmental condition of a building. The integrated device includes a valve configured to regulate a flow of a fluid through a conduit and an actuator. The actuator includes a motor and a drive device. The drive device is driven by the motor and coupled to the valve for driving the valve between multiple positions. The integrated device further includes a processing circuit coupled to the motor. The processing circuit is configured to detect device identifying information for the valve or the actuator and to detect the integrated device location within the building.

Abstract: A fire damper actuation system in an HVAC system includes a damper system and an actuator system. The damper system includes damper blades rotatable between an open configuration and a closed configuration, a crank arm assembly configured to drive the damper blades, a spring assembly configured to be held in a loaded condition when the damper blades are in the open configuration, a temperature-activated fusible link, and a fusible link arm coupling the temperature-activated fusible link to the crank arm assembly. The actuator system includes a motor and a drive device. The drive device is coupled to the crank arm assembly and the temperature-activated fusible link. Operation of the drive device by the motor between a first end stop location and a second end stop location simultaneously rotates the crank arm assembly and the temperature-activated fusible link to complete a test inspection procedure.

Abstract: A valve assembly is provided. The valve assembly includes a valve body having a valve chamber and a plurality of ports into the valve chamber. The plurality of ports include a first port, a second port, and a third port. The first port and the second port are aligned with a common axis and located on opposite sides of the valve chamber. The system further includes a valve member located within the valve chamber. The valve member is a rotatable ball having a fluid passage that extends through the ball and includes an opening at the end of the ball. The fluid passage is substantially oval-shaped when viewed at the opening in a direction parallel to the fluid passage. The valve assembly further includes a valve stem that is coupled to a valve member and has a first end that extends from the valve body.

Abstract: A multipurpose valve tool is provided. The multipurpose valve tool includes multiple flow control discs, a retention ring, and a valve key. The flow control discs are configured to be installed within a valve body of a valve assembly to modulate a flow of fluid through an outlet port of the valve body. The retention ring is configured to retain the flow control discs on a component of the valve assembly when the flow control discs are not installed within the valve body. The valve key includes a first end configured to engage an installation feature in a retention fastener for one of the flow control discs. The flow control discs, the retention ring, and the valve key are detachably coupled to each other.
